Our gold pick, which is the Nulaxy Bluetooth FM transmitter, is a quality device that is loved by customers and critics alike. It is a lightweight device that you will not mind transferring between cars, as it only weights about 3.2 ounces. It is 6.4 inches in length, 4.9 inches in width, and 2.1 inches deep, which means that it will not take up a lot of space in your car.

Aesthetically, this device looks a little alien compared to most devices that we connect to our vehicles. It has a circular portion that connects to the cigarette lighter. This part also has a USB slot that allows you to charge your smart phone or other portable devices. Then, there is a bendable tube that connects to the section of the unit that has the display and the control features. The LED display is at the top of the main section, and it is capable of informing you which artist is currently singing and the song that you are listening to.

Beneath the display there is a volume knob that can be turned to adjust what you hear, but it can also be pressed once to answer an incoming call or pressed two times to ignore it. There is also a button that lets you adjust the frequency that you are using as well as a button to switch tracks. These buttons all glow blue, which allows you to see them better when you are driving after the sun sets.

On the left side of the unit, there is a microphone that can be used instead of your phone, so when a call comes in, you can easily press the button on the Nulaxy FM transmitter to take the call and talk to the individual who called you without the need to hold your phone. The right side of the device features a TF/SD card that allows you to transfer songs directly to the transmitter, without using an MP3 player or another music capable device. There is also an auxiliary input and output option that can be used, which is a needed feature for someone who does not have Bluetooth capabilities on their MP3 player.

This unit has a frequency range between 87.5 megahertz and 108 megahertz, which gives you a full range of options when you are selection a location to broadcast your music. The Bluetooth functionality of this device reaches about five meters, so you do not have to have your device on your lap while you are driving. It also has a frequency distance of two meters, which means that the car next to you at the stop light will not pick up your signal.

This Bluetooth FM transmitter is compatible with most Apple and Android devices as well as MP3 players and digital cameras. Once the device is turned on, it will begin automatically paring with a device in range that is compatible. When you are getting your playlist ready, make sure to remember that this device needs files to be in MP3 format or WMA format. One great aspect of this unit is that it is designed to suppress excess wind and sounds to give you a better listening experience.

You can purchase this transmitter in either black or gold, whichever color matches the interior of your vehicle best, and it comes with a one year warranty in case there are any issues in the first twelve months of ownership. When it comes to reviews, there are over 850 posted on Amazon alone, and 88 percent of them have given this device a positive four or five star rating. Many of the users have expressed how clear the audio quality is when using this device and how easy it is to set up.

Here is an example of one five star review: “OK, just received it and used it — this thing is legit. The one I got has excellent sound and connects automatically; just had to find the right volume adjustments for the apps, the iPad, the Nulaxy, and the radio. You want a moderate level on each, and then use the radio volume for fine adjustments.”

Here is an example of one such five star testimonial: “Super quick to set up, the remote makes controlling it a breeze, and it actually provides a very good quality when you tune to a frequency that isn’t used in your area. It has a fairly broad frequency range, I believe between the mid 80’s and up to about 110 (FM of course).”

Pre-purchase considerations

Transmission Range and Frequency Spectrum

The range that your transmitter can reach is important. Most Bluetooth FM transmitters have a range that can vary between ten feet to about 30 feet, which should reach the entire length of the vehicle that you are driving in. Be aware that if the range is at the high end of the spectrum, there is a possibility that you will pick up other signals. This can be annoying if a car pulls up using the same frequency when you are listening to your favorite song.

To make sure that you have the best chance of having a clear signal to broadcast on, it is important to purchase a Bluetooth FM transmitter with a full frequency spectrum. This means that you will be able to access any free channel from 88.1 to 107.9 megahertz. This can be extremely useful for anyone who lives in a highly populated area where a lot of the frequencies may already be taken.

Sound Quality

The sound quality that you receive will vary based on a few things, like the distance that the transmitter is from the antenna. To make sure that you have an optimal audio experience, make sure that you look for features like noise filters, which are a great way to minimize or eliminate and static or excessive background noise. Equalizers are also a feature that is becoming more standardized on Bluetooth FM transmitters, so make sure that it’s a feature that you look for to get the best sound quality that is available to you.


There are Bluetooth FM transmitters that feature a display that lets you know what song you are listening to as well as the artist who is singing. Many cars have this feature, but if you like to know information about the songs that you are listening to, then you may want to find a transmitter that has this functionality as well.

Functionality and Ease of Use

Most Bluetooth FM transmitters connect to your MP3 player, but there are also some devices available that cut out the need for an external audio player. The playlists can be created and stored on the memory card in the transmitter, and then it will be sent to your car stereo to be listened to. If you do want to connect your audio device, then you may want to ensure that your device is compatible with the transmitter you purchase. Some Bluetooth FM transmitters also come with a remote, which allows you to easily operate the device while you are in the car.

Power Requirements and Ability to Save

You will need to power your new Bluetooth FM transmitter, so why not make sure that it can easily be powered in your car. If you have a device that requires 12 volts of power that means that you can use the car’s cigarette lighter to power it. There are also options that use your MP3 player or cell phone’s battery, but they tend to drain the device the music is being played from quickly.

Having the ability to save the frequency that you use near your home is a feature worth having. It means that you can quickly switch back to the frequency you use after trip away from home without being required to surf through channels to find one that is free. Also, some devices automatically switch frequencies when a station begins to cause interference.

Music is a part of all of our lives, so why not make accessing your own music easier, especially when you are on a long road trip.
